Replace Serial

Explanation

This activity is used to replace a serial in a serial structure. Before a serial can be replaced in a serial structure, observe the following guidelines for more accurate replacement of the serial.

• A serial with an operational status of Planned For Operation can be replaced with a serial that has any of the following operational statuses: Planned For Operation, In Operation, Out Of Operation.
• A serial with an operational status of In Operation or Out Of Operation can be replaced with a serial that has any of the following operational statuses: In Operation, Out Of Operation.
• A serial with the operational status Scrapped cannot be used to replace another serial.
• The serial to connect cannot be locked.
• A serial can only be replaced with the same prime part or with one of its alternates (position or template alternate). If an alternate is to be replaced, it can be replaced with the same part number or another alternate, i.e., an alternate to the part being replaced. Note that when you are performing a replace, the rules of interchangeability will not apply to serials that are Planned For Operation, i.e., the serials can be replaced with any prime parts or any valid alternates defined for the structure position to be replaced. For more information, refer the activities Define Alternate Parts per Position and Define Alternate Parts in Template.

If access control is established, you can only replace the serials to which you have access. Establishing access control is done by assigning a user to an access group defined in basic data. The access groups will be used to extend access to all or selected parts and serials in a structure. When a serial is removed from a serial structure, you can specify the access rights you want to keep for it. You can select to either keep the current access rights for the serial, update the serial with the default part access, or select the access groups you want to keep for the replaced serial.

Depending on your workflow, you can perform this activity by clicking the option Perform Structure Change from one of the following pages.

• Manage Serial Structure
• Serial Initialization
• Perform Structure Change
• Execute Work Task
• Flight Log/Fault

Following is a description of the information that can be entered in each assistant step.

Step 1 - Structure Change Selection

• Select the replace serial option from the structure change section.
  
  Note: If you are using the Perform Structure Change assistant page, Execute Work Task page or the Flight Log/Fault tab to perform this activity, first you have to select the serial for which you want to perform a structure change. If the structure change is to be performed further down in the structure of the selected serial, enable the Perform Structure Change for Sub Serial option and enter the required sub serial details.

Step 2 - Structure Change Details

• Serial information for the structure in which the serial is to be replaced appears automatically in the Remove or Swap from section. The structure position in which the serial is to be replaced is displayed. If needed, this value can be changed.
• You can enter the location in which the disconnected serial (as a result of the Replace) is to be placed. If needed, select a new operational condition for the serial that is to be replaced in the structure.
• In the Install or Swap into section, enter the part number of the serial that you want to replace. When you enter a value in this field, the serial number and installation date appears automatically.
• Enable the Print Serviceability Tag option to order and print the serviceability tag report for the serial being replaced. Note: If the value of the PRNT_SERVICE_TAG_ACS object property in System Definition/Object Properties is set to TRUE, this option will be enabled by default. The value of this option can be changed, if needed.
• Enter the workshop responsible for replacing the serial. If you want to connect replacing of a serial to a maintenance event, enter a value for the Mx Event Number field.
• Enter the date and time the structure change is to be performed. Enable the Unscheduled Removal option if this structure change is to be an unscheduled removal.
• Enable the Keep Current Access option, if you want the serial that is to be replaced to keep its current access rights. This option will be enabled by default. Disable this option if you do not want the replaced serial to keep its current access. When this option is disabled the Default Access Groups option will be made available.
• Enable the Default Access Groups option, if you want the replaced serial to keep its part access. This option will be enabled by default. Disable this option if you want only a selected number of access groups to keep the part access when the serial is replaced.
• Enable the Run in Batch option if you want access rights for the replaced serial to be updated through a batch job.

Prerequisites

• A disconnected serial with the correct status and configuration must exist. A serial can only be installed in a serial structure whose configuration (serial structure template) allows it to be installed. This means that a part number or revision combination not existing (as prime part or alternate) in a level in the serial structure template cannot be installed in this level in the serial structure, and vice versa. For more information, refer to the activity Define Template Part.
• If you want a location code to be displayed automatically when performing a structure change on a work order, the location code must be connected to the workshop to which the work order is distributed. This should be done in the Location Codes per Workshop page.

System Effects

• The disconnected serial is installed in a serial structure, while the replaced serial is no longer in a serial structure. A replacement historical record will be created.
• If the serial installed is defined as an alternate with interchangeability rule Qualified Interchangeable, the alternate must be approved before the operational condition for the structure can be set to Operational. For more information, refer to the activity Approve or Reject Structure Change.
• If the installed serial is part of the minimum configuration and has the Non Operational operational condition, the parent serial of the structure in which it is installed will also receive the Non Operational operational condition.
• If the structure change is performed from a work order, a mismatch record will be created if the removed serial is not installed in the parent serial.
• If the structure change is performed from a work order, a mismatch record will be created if the installed serial is installed in another serial.
• The disconnected serial will receive the current access rights by default, or the specified access groups defined for the serial.
• If the Print Serviceability Tag option is enabled, the serviceability tag is printed for the serial being replaced. The tag can be included with the serial when it is kept in a facility. Serviceability tag refers to the tag used in the Aviation industry to clearly identify an uninstalled component or assembly and its current status. The serviceability status is automatically determined by the system based the operational status and operational condition of the serial. Therefore,
  • If the operational status of the serial is Scrapped, the serviceability tag is printed with the Scrapped serviceability status.
  • If the operational condition of the serial is Operational, the serviceability tag is printed with the Serviceable serviceability status.
  • If the operational condition for the serial is Non Operational, the serviceability tag is printed with the Unserviceable serviceability status.
